How do I deal with the noise

Hi all, i am new to octane, but I have had this reocurring Problem in every interior I have rendered so far. I do mainly shops - no or little natural light and I have never managed to get a clean noiseless shot. As a result i have had to work a lot in Photoshop. This is the ceiling of my latest project. Can someone help me with this.

Direct light


Image took 3 hours to render and I always get grainy artifacts close to the lightsources.

Path tracing 3 hours again,
My boss doesn't allow me to post the full images

Here are the Kernel settings

I have tried to push every setting i could think of.
The most useful ones were GI clamp and Path termination, but the Problem is not completely gone.

Hi viki_niki,
the issue comes from the recessed spot light, please, have a look at this other discussion on how to drastically reduce the complexity and noise:

Sorry, it's from c4doctane, let me know if something is not clear.
ciao beppe
